Alright I understand what you are asking. However this is a very broad question you are asking, but I will try to answer you.
Amenities - I don't know how much you are spending per room but this is generally the basics- bathroom amenities is a must-shower gell, body lotion and tooth brush set. Soap is great!
Clean bathroom please!! Clean sheets and fresh smelling room . Stale smelling rooms are put off. Bathrobes x 2 are great along with slippers as well. Are we having a safe as well? I m a tea lover so I'd love it if there is a tea maker in the room with tea and coffee things.
Amenities change as per the category of the room as well so - are there categories of rooms? This is most basic standard I would expect.
Ambience- I would like to feel safe, cozy at the same time relaxed. If I'm with someone, even better coz I'd be asking a double occupancy single bed instead of twin sharing.
Is there a good view? Is there a balcony? Can we sit out?
This off the top of my head. But as I said you have asked a very broad question and there's no limit to the amenities.
Have I answered your question in some way? @HunterUncle let me know if you wanna know more.
